dynamicInsert

Purpose

Whether to dynamically build INSERT queries

Examples

class Book {
static mapping = {
dynamicInsert true
}
}

Description

Usage: dynamicInsert(boolean)

By default Hibernate will build all queries at start-up time and cache them, which represents a significant performance gain as queries don't have to be dynamically generated at runtime. However, there are certain circumstances where dynamic queries are useful.

For example if you were using custom UserType to hash passwords, every time an UPDATE occurred, the password would get re-hashed. The dynamicInsert method allows you to turn of the dynamic creation of queries that uses only the properties that are needed to perform the insert.
